Wow! That sounds complicated. What happens if something in the system breaks? Would that leave you stranded?
I use a much simpler security solution. I drive a crappy old much-dented ****box with sun-damaged paint and I avoid washing the outside of my car. Nobody has tried breaking into my car yet - even when I forget to lock the doors or roll up the windows completely.
The most high-tech modification I have made was to wire up the immoboliser to an OEM-looking automotive switch that blends in on the dash in plain sight. That should deter bored kids from taking my car for a joyride, or slow down a thief if my keys get stolen.
A determined enough thief will always find a way to steal your car, imho.
